WHY IT NEEDS A POLICY

Why pylon_create_tag needs a policy

Creating a tag is a reversible write operation. Tags are metadata used for organization and filtering; creating one has minimal blast radius. An AI could create spam tags or clutter the tag namespace, but this is low-impact compared to financial, destructive, or execute-level risks. Confidence is high because the description is clear and the intent unambiguous.

From the tool's definition Tool description states 'Create a new tag' — a straightforward creation operation that adds a new categorization resource without modifying or deleting existing data.
